How to use Gas Leak Detector (GD-3300)

The READY light is glowing right after you switched on the Combustible Gas Leak Detector by sliding the ON/OFF button in fresh air. The instrument runs through a one-minute warm-up and self-zeroing sequence. The Reed GD-3300's alarm may be very loud without contact with any gas, that is caused the initial preset sensitivity.

Rate (Sensitivity) Adjustment
You should conduct a quick functional test before using the instrument and adjust the tick rate to non-alarm level. Then, simply expose the sensor to a known leak, ( you can use a cigarette lighter fpr this test). After the initial warm-up, the instrument can be used to detect combustible gases. When the sensor in the probe tip detects a combustible gas, the tick rate will increase and the instrument sounds a warbling tone while the ALARM light. As the concentration of gas increases, so does the tick rate.

Adjusting the Tick Rate (Sensitivity)
When the GD-3300's sensor is getting close to a gas leak you will know this by the tick rate. You can control the tick rate using the rotary wheel in the center of the instrument. For doing this just move the wheel clockwise to increase the frequency or counter-clockwise to decrease the frequency.
